Hi,
So, one of my pcs died and motherboard was making no beepings so I ordered a new motherboard which I got about 1 week later.
Then I removed the heatsink and it pulled out the AMD FX 8350 CPU with it.

I have tried everything as suggested on the internet to remove a fused cpu to heatsink. I have tried dental floss. I also soaked it in isopropyl alcohol for nearly 24 hours after trying shorter time. Still it would not budge.

So as a last resort i have tried some more drastic measures trying to twist it using flat blocks on either side, and that wasn't working so i tried to lever it up from one side using a flat ruler.

And well, it came off, but not in a good way. The silicon wafer with the pins is now separated from the metal CPU base, which is STILL fused to the heatsink.

Now I do wonder guys, is this CPU now totally destroyed? It looks like all that was holding the wafer to the cpu metal base was glue though, so I am not sure. Is it possible to glue it back together if i can somehow get the metal base removed?

You delidded a IHS directly soldered to the die!
The CPU is dead. Ripped into half in the lateral direction.
But you should have used a hair dryer to soften the glued up paste and a X-Acto Knife to slice the CPU off the heatsink.

You can still salvage the heatsink though. But I doubt the CPU will work with its die exposed like that. You could try, cause silicon is glassy and transparent and you better pray that only the Indium on the die is ripped off. (Odds are near zero)
